This invention relates to a clamp-and also to a method of makingthesam-e, one, of the ob ects being to provide a clamp which can he cheaply and quit constructed and constitutes an ellicient meansi'or gripping a est, strut or the like for the purpose of connecting guy wires and other bracing means, etc, to the engaged structure.

Another object is to sin'iplity the method of producing the-clamps wherebyopposed eyes forming a part of the clamp and dosigned'for the reception oit a clampingubolt, will accurately aline so as to permit ready insertion of the bolt. i With the foregoing and other objects in view which will appear as the descripi" Jion proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described ii; and claimed it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from r the spirit of the invention.

N In the accompanying drawing the preferred form of theinvention has been shown.

In said drawing,

Figure 1 is a side elevation of the clamp, the same being shown in position on a tubular structure, the tie bolt being shown in section.

Figure 2 is an end view the clamp, thc tubular structure engaged thereby being shown in section.

Figure 3 is a central transverse section F3 through the clamp, the'bolt being removed.

Figure 4: is a detail view of the blank from which the band portion of the clamp is formed.

Figure 5 is a front view oi? the blank after it has been bent preparatory to tho completion of the clamp. V

Figure 6 is a detail View of a tubular eye member used in the manufacture. of the P clamp. I I V Figure 7 is a section showing the tubular eye member assembled with the band prior to being joined thereto, g

In carrying out the invention there is provided a strip of metalindicated at 1 and in 50 each end of this strip there is formed a short slot 2 terminating in a rounded enlargement 3. In addition to thestrip 1 there is also provided a length of metal tubing designated ate and the middle portion of this tubing is formed with an annular concave portion 5.

Bandl is bent to substantially circular form as shownin Figure 7 and the tubular eye'member lis then laid on the ends of the band so as to rest withinthe slots 2 and their enlarged portions 3. hen thus located the concave portion 5 of the tubular eye member will be substantially concentric with the center about whichthe band is bent. Vith the parts thus assembled the parts can be joined by welding, it being preferred to apply metal between the ends of the tubular member and the band as shown at 6 and fuse this metal so as to join the parts. Following the welding operation, a transverse cut can be made through the tubular member by means of a saw or other tool so that the end portions of said member will be separated to form eyes, one eye being carried by each end portion of the band.

The eyes, when assembled with the band in themanner described, will always be properly alined so that no difliculty will be experienced in inserting a clamping or tie bolt 7 through the eyes when it is desired to bind the clamp about a post, strut, or othcrstructure indicated generally at A.

WVhat is claimed is The herein described method of producing metal clamps which consists in slotting the ends of a metal band and bending the band to bring the ends adjacent to each other, thereafter applying to the slotted portions of the band a tubular member bridgingthc space between the ends of the band, subsequently joining the tubular member to the ends of the band by fusing, and finally dividing the tubu larmember at its center to form alining eyes.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
